Question

我正在使用VbScript来检索Win32_Service的securitydescriptor。我使用以下代码：

 SE_DACL_PRESENT = &h4
 ACCESS_ALLOWED_ACE_TYPE = &h0
 ACCESS_DENIED_ACE_TYPE  = &h1

 strComputer = "."
 Set objWMIService = GetObject("winmgmts:" _
  & "{impersonationLevel=impersonate, (Security)}!\\" & strComputer & "\root\cimv2")

 Set colInstalledPrinters =  objWMIService.ExecQuery _
  ("Select * from Win32_Service")

 For Each objPrinter in colInstalledPrinters
    Wscript.Echo "Name: " & objPrinter.Name 
 ' Get security descriptor for printer
  Return = objPrinter.GetSecurityDescriptor( objSD )
  If ( return <> 0 ) Then
  WScript.Echo "Could not get security descriptor: " & Return
  wscript.Quit Return
  End If
 ' Extract the security descriptor flags
  intControlFlags = objSD.ControlFlags
  If intControlFlags AND SE_DACL_PRESENT Then
 ' Get the ACE entries from security descriptor
   colACEs = objSD.DACL
  For Each objACE in colACEs
 ' Get all the trustees and determine which have access to printer
   WScript.Echo objACE.Trustee.Domain & "\" & objACE.Trustee.Name
   If objACE.AceType = ACCESS_ALLOWED_ACE_TYPE Then
    WScript.Echo vbTab & "User has access to printer"
   ElseIf objACE.AceType = ACCESS_DENIED_ACE_TYPE Then
    WScript.Echo vbTab & "User does not have access to the printer"
   End If
  Next
  Else
  WScript.Echo "No DACL found in security descriptor"
 End If
 Next

但是，每次我运行它时都会收到消息，说明生成的代码是-2147023582，而不是定义的错误代码 the manual

有人有任何想法吗？我使用的是Windows 7专业版64位。

该数字是-2147023582。它可能是某种64位问题吗？这看起来像无符号整数存储为有符号整数吗？

（PS：不介意变量名......我从msdn中删除了一个例子）。

Answer 1

错误代码-2147023582（0x80070522）表示“客户端未持有所需的权限”。最有可能的是，WMI名字对象中的Security权限是不够的，您需要以管理员身份运行脚本。（至少，当您以管理员身份运行时，您的脚本在64位Vista上运行正常。）
